Facebook continues to grow at a meteoric pace, adding 50 million new members each month. Now it has 500 million, according to the company. 

The company's rapid ascension -mostly due to its effort to change and improve the service- doesn't mean it is a cool brand. On the contrary, the most visited site on the Internet may be also the most despised.

A new poll done by the University of Michigan says the site scored 64 on a 100-point scale, which "puts Facebook in the bottom 5 percent" of private sector companies "and in the same range as airlines and cable companies, two perennially low scoring industries with terrible customer satisfaction."

Why is that? Well, Facebook is under fire for everything from the ways it shares data to changing the site around frequently so that regular users are confused and frustrated.
